Which particle controls the type of atom?
protons
Atoms are composed of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are themselves composed of quarks. The number of protons determines the element of the atom, the number of neutrons determines the isotope, and the number of electrons determines the ionization state.
What particle is the boss of the atom?
Proton
Proton is the boss of the subatomic particle due to the following reasons.
What is a particle of an atom called?
Overview of Atomic Structure. Atoms are made up of particles called protons, neutrons, and electrons, which are responsible for the mass and charge of atoms.
Which particle is responsible for the behavior of an atom?
Electrons
Electrons occupy the lowest available energy levels, that is to say the closest to the nucleus, but each energy level can only contain a limited number of electrons. The position of the outermost electrons is key in determining the behavior of an atom.
What particles affect the charge of an atom?
The charge of an atom is determined by the ratio of protons to electrons.
What particle determines the identity of an element?
Explanation: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes.
What subatomic particle is responsible for determining the mass of an atom?
Together, the number of protons and the number of neutrons determine an element’s mass number. Since an element’s isotopes have slightly different mass numbers, the atomic mass is calculated by obtaining the mean of the mass numbers for its isotopes.
What particles make up nucleus A?
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks.
What are the 4 subatomic particles?

| Subatomic particle | Symbol | Location |
|---|---|---|
| Proton | p | inside the nucleus |
| Neutron | n | inside the nucleus |
| Electron | e- | outside the nucleus |
What subatomic particle is responsible for the identity of the atom?
proton
The proton determines the identity of an element.
Which particle in an atom is most responsible for its chemical properties?
electrons
The electrons are most responsible for the chemical properties of the atom and are located outside of the nucleus.
Which particle determines the stability of an atom?
The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in the nucleus. The principal factor for determining whether a nucleus is stable is the neutron to proton ratio.
What are the three main particles of an atom?
The three main sub-atomic particles of an atom are proton, neutron and electron. The mass of a proton is about 1800 times the mass of an electron and the masses of proton and neutron are almost similar.
What makes up the middle of every atom?
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus.
Why does an atom have a certain size?
A stable atom has a certain size so that any equation describing it must contain some fundamental constant or combination of constants with a dimension of length. The classical fundamental constants–namely, the charges and the masses of the electron and the nucleus–cannot be combined to make a length.
Which is atom is responsible for the chemical behaviour?
In that case we can attribute most of the chemical variability between elements to the electron. Also low temperature matters. Within molecular clouds in space, where temperatures are very low, the nuclear isotopic mass and spin does play a significant role in their chemistry. The entire atom is responsible for chemical behaviour.
